Ganymede - Voyager 2

Color image of Jupiter's moon Ganymede from 6 million km

Voyager 2 image of Jupiter's largest moon Ganymede.
This image was taken on 2 July 1979, from 6 million km,
6 days before Voyager 2's closest approach to the
satellite. The light bluish regions near the north and
south poles are visible in this image, possibly a result
of water ice or frost. Ganymede is 5,300 km in diameter.
